How to prevent Mobile App crashes with testing

In this modern and advanced digital world, different mobile applications have become a vital part of our daily lives, whether it is entertainment or knowledgeable applications. Social media apps, e-commerce or e-banking apps, or entertaining content platforms, all such applications have been used by billions of people every day and it’s gradually rising.With the gradually rising usage of such apps, the app developers ensure the application’s stability and performance to grant its users the best experience. However, at times apps get crashed or malfunctioned which leads to a poor user experience, bad reviews, and disastrous loss in revenue generation. To avoid and prevent app crashing, mobile app testing has been used by developers, to create and launch stable and functioning apps.

Mobile app testing includes the analysis of the functionality and performance of applications, their user experience and usage, and their working across various platforms. Developers with perfect testing strategies can create a flawless app without any crashes or errors and provide the user with a seamless and enhanced experience.

Before getting into mobile app testing, let’s explore different types of application development services and companies. Services for applications like React Native and Flutter apps, which can be customized and launched, performing under different OS, either Android or iOS.

A well-organized strategy is essential for comprehensive mobile app testing, and now let’s move on to the main reasons for app crashes.

Main Reasons for App Crash

The significance of mobile app testing clearly shows how often the app crashes and it’s essential to know the main reason why crashes happen. There are multiple reasons for app crashes and we’ll discuss a few of them below:

Bugs in code

Several errors or bugs in the coding sequence cause the application to freeze, malfunction, or crash.

Non-compatibility with OS

With a massive amount of different mobile devices and operating systems, it is crucial for an application to be compatible with either Android or iOS or with both. If an app isn’t compatible with mobile devices, with different hardware or OS versions then it leads to performance errors and crashing.

Memory leakage

Some mobile applications are unable to manage memory which leads to leaking of it and that’s how the application’s performance starts to degrade and decline which causes it to crash.

Poor quality network

Mobile applications work with internet connections or network connectivity for data exchange. However, low-quality internet or weak network signals cause data loading issues and lead to application crashes.

Depletion of Resources

Excessive use of any resources like battery or CPU leads to depletion of that particular resource which leads to app malfunctioning and instability, and eventually crash.

Incompatible User Interface

It is disastrous for an app if its user interface is incompatible with different screen sizes and orientations that distort the display, instability, and cause crashes when users interact with the app.

These are the clear reasons why an application undergoes crashes and malfunctions. Mobile app testing performs a comprehensive process to resolve every error or bug in different stages of app creation and prevent it from failing and crashing when users interact.

Detects when an application crashes

Now after we know the main reasons why an application crashes, a user should be able to detect app crashes and should be aware of what happens when an app crashes.

When an application undergoes a crash it behaves differently and malfunctions, so let’s discuss such misbehaving features when an app crash:

App discontinuation: Whenever an app closes or terminates suddenly, it indicates that the app is not responding and has been stopped. This behavior shows an app crash.

• Logging of errors: A stack trace or error log takes place right after the crash, which records the exact point in the code where the crash occurred. This feature is really important for developers to detect app crashes and be able to resolve the cause.
• Application unusual behavior: Sometimes the app does not fully close but freezes at a particular point or becomes unresponsive, which is also considered as an app crash.
• Data loss: Abrupt closure of an application can often lead to loss of previous data and the app restarts from the initial phase. This loss of data and progress also indicates that the app was malfunctioning and crashed.

Detect app crashes in Android

For Android, there are crash reporting tools like Firebase Crashlytics, Sentry, etc which can be used by developers to capture crash reports. By those reports, you can detect the crash along with device information, stack traces, and information about the conditions at which the crash occurred. It makes it easier for the developers to detect and diagnose the issue.

Application not responding error (ANR) is another sign of an app crash in Android OS. The crash report and statistics for the app can be obtained through the Google Play console and allow you to distinguish stability errors from real-world usage.

Detect app crashes in iOS

One of Apple’s official beta testing platforms which give the application to various testers and gather the crash report. The crash report helps the developer to detect and identify where any crash occurred and resolve it. Secondly, crash logs which contain stack traces, device info, and OS version are submitted to the App Store connect so the developer can review them afterwards.

Xcode Debugger

Xcode debugger provides essential tools to track and debug crashes in iOS apps. During development or testing whenever an application fails to proceed or crashes Xcode will provide the stack traces to help the developer identify the issue and solve it.

How to fix App crash

Mobile app testing is very essential to prevent and fix the app crashing to enhance the application’s performance and stability. It includes a variety of testing to verify that the app is working as expected under difficult and usual conditions like different screen sizes and devices, OS versions, or network quality.

Testing basic functions

This test confirms that the app is working as intended and focuses mainly on functionality ensuring that user activities like logging in, performing transactions or form submission must be performed smoothly. Functional testing can also identify any bugs present in the code that could lead to an app crash.

Testing app performance

It focuses on how well an application works in various conditions like high load, varying network speed and quality, limited system resources, etc. bad performance under these conditions indicates that the app might crash and developers will tend to fix it.

Compatibility test

Nowadays there have been many mobile devices, screen sizes, and OS versions have been introduced. The compatibility testing of apps should be done to verify that the application is compatible with all these features. Apps should be compatible and work smoothly in different variations like screen sizes, resolutions, and OS versions without crashing or distortion. Compatibility testing minimizes the chances of app crashes and ensures that the app functions well.
